Abstract

Methods for dispensing eyeglasses are disclosed. The methods involve making a subjective refraction and an objective refraction and Sending the information to a calculation computer to combine both retractions to calculate the person's prescription. The person's prescription is subsequently sent to a manufacturing location separate from the calculation computer for manufacture of the lenses.
